Anthocyanins and flavonoids, in general, have a protective role from UV and oxidation on plant and animals. Anthocyanins are found abundantly in some plant but not all plants. The reasons for these differences in concentration are not well understood. In Dahlia flowers (Dahlia variabilis hort.), Anthocyanin formation is depending on the expression of genes such as flavanone 3β- hydroxylase (FHT), which hunts precursor molecules toward the anthocyanin pathway. The aim of this project is to investigate the FHT gene expression in eggplant (Solanum melongena L.) to see if the up-regulation of FHT expression correlates with an increase in anthocyanin production. Quantative PCR was performed to measure FHT and IVS (transcriptional activator) gene expression. The differences in the mean of FHT and IVS expression between purple versus white eggplant were significant.
